In order not to forget important dates, such as events or meetings, we can create our own appointments in the calendar app of the OnePlus smartphone.

When you create an appointment, you first select whether it is an appointment, task, reminder or destination, then you can choose any name or title, date and time, and other options such as location or recurrence.

Depending on which appointment option is selected, people, further descriptions or note attachments can also be added.
